PWS-711-1R Supermicro Active 710W 1U Server PSU

DC-Input 1U ATX Server Power Supply for Telco Edge Deployments with the PWS-711-1R

The PWS-711-1R is a 710W DC-input ATX server power supply engineered for -48V plant environments where centralized rectifiers and battery-backed DC buses are standard. Designed for single-PSU server builds, the PWS-711-1R enables cost-optimized edge and telecom nodes that prioritize predictable power delivery and straightforward serviceability in 1U chassis designs.

With a wide -36 to -75 VDC input range, the PWS-711-1R aligns to variable DC bus conditions while maintaining stable output regulation for modern CPU platforms, memory subsystems, and PCIe expansion backplanes that are sensitive to transient behavior. Fixed, non-modular cabling reduces connection points and simplifies qualification for consistent builds. Active power design and up to 89% peak efficiency help manage rack-level thermal budgets, while integrated protection mechanisms (OVP, OCP, SCP) support fault containment across storage-heavy configurations and mixed PCIe I/O profiles.

Why Choose the PWS-711-1R?

The PWS-711-1R delivers an enterprise-ready DC power foundation for dense edge servers where AC conversion at the rack is undesirable. It supports efficient capacity planning for non-redundant nodes, reduces integration risk in -48V sites, and provides a pragmatic density-to-reliability balance for distributed deployments that scale by replicating standardized server images and power components.

Supermicro designs power subsystems with a focus on electrical stability, platform compatibility, and long-life operation in data centre and telco conditions. The PWS-711-1R reflects this approach through standardized ATX integration, protection coverage, and predictable behavior for service teams maintaining uniform hardware fleets.

Key Applications:

• -48V DC telco edge servers
• Single-PSU 1U server builds
• DC-powered micro data centres
• ATX replacement PSU for enterprise servers
